The physicians, nurses, scientists and staff of the National Heart, Lung and Blood Institute (NHLBI) at the National Institutes of Health (NIH) welcome you to our NHLBI Trials page for patient recruitment and trial information. We conduct a large number of research studies with patients who have diseases of the heart and blood vessels, lungs, blood cells and bone marrow, or cholesterol. Our studies are performed at the NIH Clinical Center (CC), a hospital dedicated to the highest quality research, in Bethesda, Maryland.
We want to provide you with information about our research and about your disease to help you decide whether to volunteer for participation in one of our studies. If you qualify for a study, then treatment, evaluation and, in some cases, transportation are FREE.
